| Re: Detailed D17 NA Build Research- COMMENT HERE!!!! Yes, when I had the stock cat on, I didn't have stalling issues. I put on the HP header with the test pipe and everything ran leaner so I had to add fuel to the entire map. The car would stall on idle bc I think it did not have enough back pressure so I had to pull some fuel out at idle. This worked fine but I would get lean misfires and i was trying to get the car running so I wouldn't throw codes. So basically I let the car run a tad rich so I wouldn't throw codes and would just feather the gas all the time at lights so it wouldn't stall. PITA but I got used to it. Oscar (DJMOTA) had to do the same thing with VAFC2 before he got KPro. Oh ya after I put back on the stock cat to pass emissions the map became SUPER rich and it just seemed like the car was choking. If you want gains with the cam ditch the cat IMO. |
